ADJUSTABLE SEAT AND DESK- Specification of Letters Patent.

Patented March 27, 1906.

Application filed July 7,1905. Serial No. 268,666-

To all whom it may concern:

Be it known that 1, JOHN THOMAS BRENT, Second, a citizen of the United States, and a resident of Cold Spring, in the county of Putnam and State of New York, have invented a new and Improved Adjustable Seat and Desk, of which the following is a full, clear, and exact description.

My invention relates to a desk and seat for use in schools and similar places.

The principal objects thereof are to simplify articles of this character by forming the main parts thereof of metal and to so put together the. several pieces of metal constituting the article as to afford simplicity of construction and strength, together with lightness, in the finished product.

Further objects of the invention will appear below.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a desk and seat constructed in accordance with my invention, showing parts in section. Fig. 2 is a rear elevation, partly in section, on the line 2 2 of Fig. 1. Fig. 3 is a sectional view on the line 3 3 of Fig. 1. Fig. 4 is a rear elevation of one element of the desk. Fig. 5 is a fragmentary sectional view on the line 5 5 of Fig. 1. Fig. 6 is a similar sectional view on the line 6 6 of Fig. 1. Fig. 7 is a plan of a portion of a seat with parts in section, and Fig. 8 is a sectional view on the line 8 8 of Fig. 4.

The article is provided with a frame consisting chiefly of four uprights 10, each upright comprising a metallic rod fitted in a bottom plate 11, adapted to rest upon the floor and be secured to it, if desired. The front uprights are connected at the top, so as to form an inverted-U-shaped piece. The frame is provided with TS 12, through which the rods 10 pass and which connect crossbars 13 of a form similar to the rods 10. On the front of the uprights is located a sliding bracket 14, which is bifurcated by means of a slot 15 and has jaws 16 to grasp the rod 10. A thumb-screw 17 is provided for clamping the jaws together to secure the bracket in any desired position upon the upright. The

form of tubes or the like.

\ are connected with hinge members 21, which directly pivoted to the pins 19.

down. The outer ends of the tubes are bent inwardly toward each other at the points 23 and are provided with sockets for receiving a piece of hard wood 24, which runs across the front of the seat.

The frame of the seat is provided with sheet-iron or other suitable material 25, the

sides of which are turned around the pipes and the front around the hard-wood piece 24. In the rear the seat is provided with a rod 26 of sufiicient size to partly counterbalance the weight of the seat and around which the rear edge of the sheet-iron is folded. Above the sheet-iron piece are preferably placed cleats 27. The manner in which the seat can be folded up and in which it is held in horizontal position will be obvious.

Connected with the top of the two front uprights is a backrest made of light sheet-iron or other suitable material. This back-rest is provided with a front piece 28, which over-' laps the tops of the front uprights and extends downwardly in a back piece 29. The bottom edge of the back-rest is turned around a rod 30, which extends along this edge. This rod is provided with rear extensions 31, which are provided with eyes 32 for receiving the uprights 10 and holding the back-rest in position. The back-rest is also provided with side flanges 33, turned over upon themselves to form a loop 34. The back portion of the back-rest is provided with vertical slots 35 to receive certain portions of the desk proper which will now be described.

Sliding on the uprights 10 are a series of One of these tubes is provided with a hand-screw 37 for holding it in adjusted positions on its upright. Each of the tubes is provided with a T 38, connected by cross-rods 39, so as to hold them rigidly together. It will be seen that the hand-screw provides means for adjusting the tubes and securing them in any desired elevation upon the uprights. These tubes support the desk proper.

The desk is provided with sides 40, of light sheet-iron or other suitable material, having their forward ends turned around the tubes 36 and riveted back to the side pieces, as shown at the points 41. The sides are com pleted by the use of triangular pieces 42, riveted to the side pieces 40. The side pieces are turned in and riveted at the point 43 to the bottom 44, which is preferably formed of sheet material and is flanged around a frame 45, which is preferably rectangular in shape and extends around the desk. The side pieces are flanged outwardly at the top and provided with screws 46 or the like, by means of which they are secured to a top 47, which is preferably formed of wood. The slots 35 of the back-rest receive the side pieces of the desk, and the portion 29 of the back-rest constitutes the rear wall of the desk. The top piece is provided with a pencil-holder 48 preferably in the form of a sheet-iron strip, having curved upper and lower edges 49. An ink-well 50, of the ordinary construction, is conveniently located in the top of the desk. The front of the desk below the top is preferably left open for the insertion'of books and other articles.

The parts are preferably made of either sheet iron or malleable iron, according to their nature, and it will be readily understood that those forming thin walls of the various parts are preferably made of the former, while those constituting brackets and supports are made of the latter. By constructing a desk in accordance with this principle the objects above mentioned will be attained and a desk which is readily adjustable to all ordinary purposes in the most simple and efflcient manner is obtained.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of a frame having uprights formed of metallic rods, a metallic desk having sockets for receiving said rods, and means for securing the desk to the rods; said desk comprising metallic side pieces bent around the uprights, and having a bottom riveted to said side pieces.

2. The combination of a frame having uprights, a desk through which said uprights pass, said desk comprising side pieces passing around said uprights, a bottom and a top secured to said side pieces, and means for securing the desk in adjusted positions upon the uprights.

4. The combination of a series of uprights, two of said uprights being formed of an inverted-U-shaped rod, a desk slidably mounted upon said uprights, and a stationary front wall for said desk having an extension passing over the front uprights and extending downwardly to form a back-rest, said backrest being formed of sheet material and having a frame at the bottom thereof engaging the uprights.

5. The combination of a series of uprights, two of said uprights bein formed of an inverted-U -shaped rod, a desk slidably mounted upon said u rights, a stationary front wall for said des r having an extension passing over the front uprights and extending downwardly to form a back-rest, said back-rest being formed of sheet material and having a frame at the bottom thereof engaging the uprights, whereby said desk can be vertically moved upon the uprights past said front wall, and a seat located below said back-rest and vertically adjustable.

7. The combination of a frame having a back-rest thereon, a pair of brackets provided with jaws for gripping a portion of the frame, means for clam ing said jaws together to secure said brac rets in any desired position upon the frame, said brackets each having a shoulder with a downwardly-facing surface, a pair of hinge members pivotally mounted upon said brackets and provided with projections adapted to engage said shoulders, a pipe connected with each of said pivoted members, and means on said pipes for supporting a seat.
